Hi Sneakerhead. You just joined the best airbrush forum and will get all the advice, support and encouragement you'll ever need here, from some great artists. Firstly as suggested already, let us know what airbrush, compressor and paints you use, and what type of painting you are interested in doing - automotive, fine art or textiles - though you would probably think it's a sin to get paint on some of those classic sneakers
. And also roughly where you are in the world, for advice on good supppliers or courses etc.
If you haven't seen them already check out the airbrush tutors vids, everything from exercises (boring, but truely the best way to get freehand skills) to projects to try, and full of helpful info on technique etc.
Don't be shy about posting up anything you do, from exercises to experiments or works in progress, no trolls here, and photos will help everyone give you tips or advice that can save you months of learning. And the best tip I can give you right now, is just to do it, no time spent with the airbrush is time wasted, building up muscle memory is key to getting good trigger control, any mistakes you make are just part of the learning and you can stumble upon useful techniques without even realising it. Airbrushing is like learning to play an instrument, and practice is the best thing you can do.
So shout out any questions - there are no stupid ones, and enjoy the forum
